Osb Vs Plywood Roof

The thickness of the plywood can be controlled by the number of plies glued together.

Osb vs plywood roof.

However when it is penetrated by water it takes a very long time to finally dry out compared to cdx plywood. Osb panels can be manufactured in lengths up to 16 feet or sometimes even higher while plywood is generally limited to 8 to 10 feet. Thankfully there are osb materials today that are designed to be moisture resistant. Both osb and plywood absolutely hate water lipinskiy mentions going on to say that the most important part regardless of which decking option you choose is that all penetration points on a roof are sealed.

How it s made plywood vs. However osb is a lot cheaper and more affordable to buy. And stayed swollen while the plywood remained stable. Today osb has 70 75 market share and plywood has about 25 share.

Compared to cdx oriented strand board osb is made very differently. It becomes soft and weak when it delaminates. Eventually you can decide which one to use between plywood vs osb for roofing. Plywood is better than osb for subfloors.

This is one of the reasons why some people prefer using plywood for their roof or subfloor.

Because of this manufacturing process osb is at least half the cost of cdx plywood. As osb is cheaper than plywood and has the strength and durability of plywood it is becoming more widely used than plywood. When it gets wet the sheathing could swell and thicken up because of the moisture. Plywood has better performance when it comes to overall durability.

Osb these sheets of wood may look similar but they are not created the same. A few other downsides to plywood. At the end it will be your consideration to choose between performance and cost. Osb boasts a more consistent density.

Unfortunately an osb is less resistant to water compared to plywood. Despite its common use as such we don t recommend using osb for subfloors but that s really just for aesthetic reasons.
